SHELL l-OR HIGH'QEXPLOSIVES;

SPECIFICATION forming part of Letters Patent No. 464,569, dated December8, 1891.

Application filed April 16, 1890. Serial N0- 348,214. (No model.)

To all whom it may concern.-

Be it known that I, J OEL GILBERT JUSTIN, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Shells for High mature explosion either in the cannon orshortly after leaving it and before striking the target.

My invention consists in the several novel features of construction andoperation hereinafter described, and which are specifically set forth inthe claim'hereunto annexed.

It is constructed as follows, reference being had to the accompanyingdrawings, in which- I Figure 1 is a vertical longitudinal section.

' Fig.2 is a transverse section on line 2.2. Fig. '3 is a like view online y Fig. 4 is a llke view on line 00 m. Fig. 5 is a vertical sectionof the body of one of the wooden boxes detached. Fig. 6 is a transversesection of r the same Fig. 7 is an isometrical view of the bottom of thebody.

This invention is an improvement upon the j shell for high 'explosivesfor which Letters Patent'were granted me, dated April 1, 1890, andnumbered 424,482, and I therefore limit and confine my specificationherein to the construction of the explosive {carrien which is mounted,suspended, and supported within the outer casing A, substantially asshown and described in said patent.

The carrier B consists of a'- cylinder the ends of which are closedbyheads, and each is provided with a flexible washer 10 and flanged disks11, secured thereon by screws 12, the flanged disks upon the rear endbeing provided with ports 14. The rear head is provided upon its innerface with central conepoint a, which fits into a seat in the center ofthe rear face of the box-supporter b, which is flanged around its outerface or otherwise adapted to engage with the base of the rear box 15,which holds the explosive. A'screw c is centrally inserted through thefront end of -the c'a-rrier B and provided with a conepoint, which fitsinto ascat in the outer face of the front-box supporter b,which is alsoflanged or otherwise adapted to engage with the top of the front box 15in the same manner as the rear supporter b.

In Fig. 1 I'show-a plate (1 interposed be-,

tween the supporterb and the end of the box and provided with a circulargroove, a like groove in theinner face of the supporter and balls e,placed in the grooves, creating a ball or roller bearing in conjunctionwith the cone-point bearing. This roller-bearing can be used on eitheror both ends, or the conepoint bearing-can be used alone, or any otherbearing the equivalent of either.

All of the boxes 15, except the rear one, if

desired, are constructed with a flanged bottom, rabbeted internally, asat g, so as to fit as acover over the externally-rabbeted top of thebox, so that each box acts as a cover for the one behind it, enabling meto fitthem closer together,'sa ving valuable space, and also operatingto better support and steady each other between the end bearings.

Theprinciplc of this improvement is that] I support orsuspend the boxesupon the front,

and rear bearings in such a manner that the outer casing A, and also thecarrier B, are free danger of premature explosion from angular rotation.a

As a further means-for preventing the friction'of the particles ofdynamite against each other I corrugate or flute the inner surface ofthe body of the box, as at h, either so that the sticks of dynamite willfit into the corrugations or grooves or not, as desired.

It will be observed that the carrier is supported inthe casing by theflanged disks and that the explosive-boxes are suspended within thecarrier between the bearings and that the tension of these bearings isadjustable, that the body of the carrier'stands clear from the innerwall of the casing and does not come BEST Alternate :30 pg into contacttherewith-5nd, further, that the casing; and having a Series of boxesfor holdboxes are suspended clear from the inner wall ing the explosivesuspended between the of the carrier. The function of this suspenends ofthe carrier, as set forth.
